Will this diet work to lose at least 15 lbs by Sept. 1?

hello, I have been having an overweight issue for ages. I used to be a diet product nuts. Until a friend recommended this method, I was skeptical at first. there was a bit of improvement for the first 2 weeks, but I felt great. After losing that first bit of weight, which was great for my confidence, I started eating right to keep off the weight completely. I couldn't believe I didn't try this sooner.
